A method and apparatus for wrapping edges of a web around rod inserts to form closure elements or profiles on the web.

Method for forming closure elements with mushroom-shaped cross sections

A heat-shrinkable envelope is composed of at least one shrinkable planar layer on which a reinforcing component of fiber-shaped or thread-shaped reinforcing elements is arranged. These reinforcing elements are arranged in unregulated configuration, for example in the form of a fleece, felt or in an irregular fill. Advantageously, a cover layer may be applied so as to sandwich and bond the reinforcing component between the cover layer and the planar layer.

Heat shrinkable envelope

The invention is directed to a heat-shrinkable envelope composed of a heat-shrinkable component and a reinforcing component that is embedded in the heat-shrinkable component and has undulations or corrugations. The reinforcing component has special arrangements for stopping tears, such as the provisions of embossments or beads, the provision of holes, punctures and slots.

The present invention relates to a seat structure for collapsible (foldable) invalid chairs provided with a flexible seat and/or back covering, comprising an upholstery material (3) and a covering material (4) at least partially enclosing said upholstery material. The covering material (4) is provided with ultrafine perforations, and an open-pore foam material shaped as a molded part is used for the upholstery material.

The device for the external (outside of the patent's body) fixation of bone fragments in the surgical treatment of fractures uses a unitary supporting bar (2) which, particularly in the case of shin-bone fractures, is positioned on the front side with a very close spacing from the bone and, for reasons of X-ray diagnosis, with a slight lateral displacement. A system of basic clamp assemblies (11), compound clamp assemblies (14) and paired clamp assemblies (12, 12a), and the thus facilitated surgical operation techniques, provide for mechanically highly stable fixation of the bone fragments being particularly careful as far as traumatizing is concerned, and being particularly favorable with respect to the psychic and physical restraint to the patient during the period in which the device is applied, and with respect to the cosmetic success upon convalescence. Due to a high degree of standardization, the system of the jaws combines cost-reducing manufacture with uncomplicated surgical operation techniques and with all possibilities for necessary corrective measures; the system favors both careful application and cosmetic success.

The apparatus serves to locate transverse holes V of intramedullary implantates, especially in the distal end of implanted interlocking nails, in the fracture treatment of bones. The apparatus includes at least one magnet (13, 16) generating an axially symmetrical field, and a magnetic field detection device (8, 9) having an axial reception characteristic, with one of said two directional elements being adapted to be aligned on the axis of the transverse hole (11) to be located. The other one of said two directional elements, e.g. the magnet (13), is freely movable exteriorly, and therefore adapted to be aligned with the axis of the transverse hole. The output signals of the magnetic field detection device (8, 9) are presented on a display device (17) through a signal processing device (15). By relative displacement of the magnet (13) and of the magnetic field detection device (8, 9), the two axes thereof may be made to coincide, which state can be displayed on the display device by a zero point indication.

The chassis features left and right lateral frames rotatably supporting at their front and rear ends front and rear wheels. The rear wheels are pivoted for steering. First and second connecting members arranged in a cross and lying in a horizontal plane extend between and are attached to the lateral frames to confine the movements of the lateral frames into predominantly parallel planes. A third connecting member extends horizontally between and is attached to the lateral frames in a position spaced above the horizontal plane so that when the chassis is viewed from the side at the most only two frame mounting points fall on a straight line. Elastic relative movement between the left and right lateral frames is achieved as a result of the inherent elasticity of the connecting members and in addition resilient mountings at the attachment points of the connecting members to the lateral frames.
